You can truly enjoy the pleasure of swimming, only if the water is warm and inviting. Heating your pool becomes a must, if you are living in a cold region. However, the cost of heating using an electric heater or a gas heater is exorbitant.
Moreover, the pool water often loses the heat and thus, has to be heated again and again. This accounts for an additional cost. A good solution to this problem would be to invest in solar pool covers, that are commonly called solar blankets.
Their working mechanism is simple. During the day, the air pouches capture the heat of sunlight, and transfer it to the water. The heat exchange easily takes place between cold pool water and the warm solar cover.
While at night, the situation is completely reverse, the cover becomes cooler while the water inside is still warm. However, its peculiar structure prevents the loss of heat, by trapping and retaining the heat in water. This reduces the loss of heat which takes place due to condensation at night.
When Do They Work
The effectiveness of the solar pool covers is directly proportional to the intensity of sunlight, and the time for which you receive it. If you get good sunlight for about 5 hours a day, you will be able to heat your water by about 1°C. Thus, within a week, you will be able to increase the swimming pool water temperature by about 10°C.
Thus, it works only when you have enough sunlight to heat the blanket, and you restrict the use of the pool, so that heat loss is not too much.
Solar pool covers reduce the cost of heating water by about 50%. However, in spite of this, they are not very popular. The reason is that, they work only in areas with ample sunlight, the areas which do not receive good sunlight hardly benefit from them.
Now that you know exactly when and how solar pool covers work, you can consider getting one, if you have suitable conditions. However, irrespective of whether or not they heat your water, you can still consider getting them. They prevent the pool chemicals from evaporating, and also keep your pool clean by not letting any debris in.
